Wheel-speed vibration in front end and possibly rear as well felt from 75 to 82 mph. This has been unsolved for 30 months I've owned the car. So far we have tried:
Alignement, twice
New Tires, twice
Front struts and tie rod ends
New rotors
Straightened the wheels at a specialty wheel shop
Road force balance, three times

Sometimes the vibration is very slight, but it comes and goes, sometimes very annoying. Steering wheel wiggles and passenger seat backrest shakes. HELP!

More than likely you have a high amount of run out on the hubs or even the wheels.

So, we need to start with checking the runout by using a dial indicator on the hubs and find out if this is the cause of the vibration.

Basically, this will cause the issue you are seeing so based on everything that has been done the runout would make the most sense.

I am attaching the complete process below on how to do this so let's run through this material and let me know what questions you have.

Thanks
